Is A Sunken Fontanelles In A 2 Month Old A Concern?

my two month olds frontal is sunken in and it’s been for a couple days. She doesnt seem like anything is wrong . tears come out when she cries , her pee doesn’t smell , her poops are regular .. she only eats 4oz every two hours she won’t eat more I’ve tried .. even tried smaller feedings more frequently.. she sleeps from 30 mins to 4.5 hours nothing longer .. she’s still a happy baby I’m just unsure if I should bring her to the hospital or not .. she doesn’t have a fever . and only wears a shortsleeve onsie at home

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.



Closure of the anterior (front) fontanel usually occurs between 4 and 26 months of age. Was she a premature baby? In preemies the closure of the anterior fontanel is delayed.



A slight depression may be present for a time after the anterior fontanel closes.



A sunken anterior fontanel is an important sign of dehydration in infants. Should she have a sunken fontanel, then she needs to be seen by a doctor right away.



Premature babies usually feed every 2 hours, but a full-term infant has a large enough stomach to take enough milk to feed every 3-4 hours. Two months of age is a regular time to have a well-baby examination. I recommend that you make an appointment with her regular health care provider as soon as possible for her check-up. The provider will check her weight and speak to you about her feedings at that time.



I hope this is helpful to you. Please return if you have additional questions.
